For used SD cards it is necessary to distinguish industrial from commercial version. Indus-
trial SD cards are usually marked with the word
Industrial
and are predetermined to de-
manding conditions. In practice, this means that industrial card can be used throughout
the range of operating temperature of SD expansion port. Another advantage is the in-
creased resistance to falls and vibrations.
